<pre>Dragonegg 3.3svn and trunk both produce undefined symbols for _iround and
_iroundf when compiling the Polyhedron 2005 benchmark aermod.f90 with...
% /sw/lib/gcc4.8/bin/gfortran -fplugin=/sw/lib/gcc4.8/lib/dragonegg.so -O1
aermod.f90 -o aermod
and an undefined symbol for _iroundf for the reflow.f90 benchmark compiled
with...
% /sw/lib/gcc4.8/bin/gfortran -fplugin=/sw/lib/gcc4.8/lib/dragonegg.so -O1
rnflow.f90 -o rnflow
against gcc 4.8.1svn with uncommitted second patch from

applied to the dragonegg sources.
These undefined symbols don't occur when dragonegg 3.3svn or trunk is compiled
against gcc 4.7.4svn. The issue appears to be due to the change...

which enabled BUILT_IN_IROUND{F,,L} on the gfortran front end.</pre>
